1. A client with type 2 diabetes mellitus is receiving metformin (Glucophage). Which laboratory test should the LPN/LVN monitor while the client is taking this medication?

Correct answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

2. When evaluating the effectiveness of a client's nursing care, the nurse first reviews the expected outcomes identified in the plan of care. What action should the nurse take next?

Correct answer: B

Rationale: After reviewing the expected outcomes in the plan of care, the nurse should obtain current client data to compare with these outcomes. This step is crucial in determining the effectiveness of the care provided. Choice A is incorrect because determining the realism of expected outcomes comes after assessing current client data. Choice C is incorrect as modifying nursing interventions should be based on the data comparison rather than done immediately after reviewing expected outcomes. Choice D is also incorrect as reviewing professional standards of care is important but not the immediate next step in evaluating care effectiveness.

3. How can self-injury be prevented when lifting a bedside cabinet?

Correct answer: A

Rationale: The correct way to prevent self-injury when lifting a bedside cabinet is by standing close to the cabinet. By standing close, the individual can maintain better control and balance while lifting, reducing the risk of injury. Bending at the waist when lifting (choice B) can strain the back and lead to injury. Twisting while lifting (choice C) can also cause strain and imbalance. Lifting with a quick motion (choice D) can increase the risk of injury due to lack of control and improper body mechanics.

4. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?

Correct answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

5. Which toy is most appropriate for an 18-month-old child?

Correct answer: A

Rationale: A pull toy is the most appropriate choice for an 18-month-old child. At this age, children are developing their motor skills and coordination, and a pull toy can help with these aspects by encouraging movement and coordination. Puzzle with large pieces (Choice B) may pose a choking hazard for a child of this age due to small parts. While a book with large pictures (Choice C) can be engaging and beneficial for language development, a pull toy is more suitable for promoting physical development in an 18-month-old. A doll with small clothes (Choice D) is not ideal for this age group as small parts can be a choking hazard.
